Reports an error in "Intraindividual variability in neural activity in the prefrontal cortex during active walking in older adults" by Roee Holtzer, Daliah Ross and Meltem Izzetoglu (Psychology and Aging, 2020[Dec], Vol 35[8], 1201-1214). In the article, the following acknowledgment of Dr. Jennifer Yuan was missing from the author note: "The authors would like to acknowledge and thank Dr. Jennifer Yuan for her previous doctoral work that relates to the subject matter of this article." The online version of this article has been corrected. (The following abstract of the original article appeared in record 2020-85077-001.) Intraindividual variability in gait and cognitive performance is distinct from central-tendency measures and associated with clinical outcomes in aging. Knowledge concerning intraindividual variability in neural activity, however, has been relatively scarce, and no research to date has reported on such variability during active walking. The current study addressed this major gap in knowledge. Participants were community-residing older adults (n = 394; mean age = 76.29 ± 6.65 years; %female = 55). Functional near-infrared spectroscopy (fNIRS) was used to measure oxygenated hemoglobin (HbO2) in the prefrontal cortex under three experimental conditions: single-task-walk, single-task-alpha (cognitive task), and dual-task-walk, which required the participants to perform the two single tasks simultaneously. Intraindividual variability in neural activity was operationalized using the standard deviation of fNIRS-derived HbO2 observations assessed during a 30-s interval in each experimental condition. The increase in intraindividual variability in neural activity in the dual-task-walk condition compared to both single-task conditions was associated with the presence of cognitive impairments and being a male. Furthermore, measures of intraindividual variability in neural activity and gait performance were positively correlated only under the dual-task-walk condition. Intraindividual variability in the neural activity of gait may be a novel marker for age-related impairments in mobility and cognitive function.

“老年人主动行走过程中前额叶皮层神经活动的个体差异”：对Holtzer等人的修正。（2020）。

报道了Roee Holtzer，Daliah Ross和Meltem Izzetoglu撰写的“老年人主动行走过程中前额叶皮层神经活动的个体差异”（心理学与老龄化，2020年[Dec]，第35卷[8]，1201-1214） 。在这篇文章中，作者注释中缺少对Jennifer Yuan博士的以下表彰：“作者要感谢Jennifer Yuan博士以前与本文主题相关的博士工作。” 本文的在线版本已得到纠正。（原始文章的以下摘要出现在记录2020-85077-001中。）步态和认知表现的个体差异与中枢倾向性测量法不同，并且与衰老的临床结果相关。然而，关于神经活动的个体内可变性的知识相对较少，迄今为止，尚无关于主动行走过程中这种可变性的研究报道。当前的研究解决了知识方面的这一主要差距。参与者是居住在社区中的老年人（n = 394；平均年龄= 76.29±6.65岁；女性百分比= 55）。功能近红外光谱（fNIRS）用于在三种实验条件下测量额叶前额叶皮层中的氧化血红蛋白（HbO2）：单任务行走，单任务alpha（认知任务）和双任务行走要求参与者同时执行两项任务。在每种实验条件下，以30 s为间隔评估fNIRS衍生的HbO2观测值的标准偏差，对神经活动的个体差异进行了运算。与两个单任务条件相比，双任务步行条件下神经活动的个体差异的增加与认知障碍的存在和男性有关。此外，仅在双任务行走条件下，神经活动和步态表现的个体差异的测量值呈正相关。步态神经活动的个体差异可能是与年龄相关的活动性和认知功能障碍的新标志。（PsycInfo数据库记录（c）2021 APA，保留所有权利）。仅在双任务行走条件下，神经活动和步态表现的个体差异的测量值呈正相关。步态神经活动的个体差异可能是与年龄相关的活动性和认知功能障碍的新标志。（PsycInfo数据库记录（c）2021 APA，保留所有权利）。仅在双任务行走条件下，神经活动和步态表现的个体差异的测量值呈正相关。步态神经活动的个体差异可能是与年龄相关的活动性和认知功能障碍的新标志。（PsycInfo数据库记录（c）2021 APA，保留所有权利）。
